For info, some of the ships in this convoy had previously arrived the U.K. with Convoy HX 117.
(See also other eastbound convoys from the same time period).

Uboat.net also lists the British Vulcain* as being from this convoy. Additionally, according to Norwegian sources, the Norwegian Borgfred took part, joining from Iceland (accordng to Arnold Hague, the British Bradglen, Cardium, and Gunvor Mærsk also joined from Iceland - see this external page about Convoy OB 318, which also names the escorts; as can be seen, Vulcain is not included here).

Ships attacked - in the order in which they appear above:(note that some of these ships were sunk after the convoy had been dispersed on the 10th. Numbers of casualties vary according to source - most numbers quoted here are from "Lloyd's War Losses")

The British Empire Cloud, was damaged by U-201 on May 9 (in the attack on Gregalia).

The British Aelybryn was damaged by U-556 on May 10 - 1 died, 44 survived.

XI also have in my possession reports re the British Chaucer and the Dutch Hercules, as follows:

Chaucer, Captain Stephen Diggins, on a voyage from Hull (Apr. 25) via Methil (Apr. 30) and Loch Ewe (May 4) for New York, is said to have been missed by a torpedo at 05:00 BST on May 10 in 59 22N 34 28W (from U-556). The track of the torpedo (fired from 2000 yards on the starboard beam) was seen ahead and Chaucer put helm hard to starboard and escaped, the torpedo passing under the bow. She had a complement of 47, all British. The captain states in a subsequent interview: "SS Aelybryn was torpedoed on my starboard side just before we sighted torpedo coming towards us. Being nearest ship we set off White Rocket as per Admiralty Instructions and gave signal on whistle. Shortly afterwards Commodore fired Very Lights for Convoy to disperse".

Captain Diggins adds:
7/5/41 - At 23 hours BST in 61 39N 24 12W Ixion and Eastern Star torpedoed. No previous warning of attack. Convoy made several emergency turns following attack.
9/5/41 - At 14 hours BST in 60 28N 32 40W Esmond and Bengore Head torpedoed without warning. These two ships were ahead of me and as I passed them we noticed men in the water shouting for help. Unable to risk stopping as I was in line of fire from attacking submarine we released three lifebuoys and one liferaft and later saw men reach raft.
9/5/41 - At 14:25 BST convoy again attacked in 60 24N 32 40W. Empire Cloud outside ship to me torpedoed and Gregalia inside ship to me torpedoed. Torpedo reported having crossed my stern. Wireless message sent out later reported that Empire Caribou was torpedoed but this was definitely an error as she was ahead of me, and ship reporting these SSS evidently mixed her up with Empire Cloud. Convoy made several emergency turns during and after these attacks.
10/5/41 - At 15:00 BST in 59 22N 34 28W Aelybryn which was on my starboard beam torpedoed. I immediately put my ship full ahead and helm hard a starboard as in all attacks two torpedoes had been fired. Almost at the same moment we sighted a torpedo coming for us. It passed very close to the stem. From the bridge it appeared to go under forefoot and others who saw it say it passed under ship. I believe the action taken by me was successful in avoiding the torpedo. Vessel was in ballast draft forward being about ten feet. Also vessel rose to swell about this time. D.G. was on all the time from leaving Hull until out of danger area. As soon as Aelybryn was torpedoed, being next ship to her we sent up White Rocket and sounded warning on whistle. Soon after Commodore sent up Very Lights for Convoy to disperse. A wireless message was received saying the Hercules was torpedoed but this was a mistake as she was next in line astern of me and it was definitely an error, the torpedoed ship being the Aelybryn.
Senior operator is of the opinion that either the Commodore or Escort Armed Cruiser sent out all the distress messages. They were definitely from the same ship.
Personally I think convoy should have been zig-zagging at least from the time when Ixion was torpedoed. Also I think ships should increase to full speed immediately an attack commences.

As mentioned, Uboat.net also lists the British Vulcain, as having originated from this convoy. She was on a voyage from Newport for Freetown with 4617 tons of coal, and was sunk on May 24 by U-38 - She had a crew of 41, 7 of whom died. 21 were detained in French West Africa, 13 repatriated to Freetown.
